AbstractCritical technology is increasingly encoded as software, exposing it to risk of loss when deployed on platforms in hostile environments. Because of this, special anti-tamper hardware may be incorporated into a device to prevent access to the software. The platform may also include insecure hardware resources, due to reasons of cost or power. There is a need to structure software in such a way that it can most effectively take advantage of both the protection afforded by the secure hardware and also the computational power provided by the non-secure hardware. In this project, we addressed the issue of protecting high-performance embedded computing (HPEC) code by partitioning it as necessary to execute sensitive portions on anti-tamper hardware. We based our software partitioning approach on Reservoir's R-Stream optimizing C compiler. R-Stream uses an innovative loop transformation framework to perform mapping and optimization of C programs to a variety of high-performance computing platforms. R-Stream is able to parallelize the static control programs that represent most of the high-performance computing application space in a way that is compatible with the goal of partitioning for execution on anti-tamper hardware.
